| Sequence stratigraphy based on Kazhdumi Formation logging data, Southwest of Iran | |
| *The article is presented in English. The Albian to Campanian sequences (Kazhdumi, Sarvak, Surgah and Ilam Formations) in Zagros basin belong to the Bangestan Group. Kazhdumi Formation with the Albian age in this basin has a particular importance due to its hydrocarbon generation potential in most of Iran's oil fields. In this research, we calculated the shale volume based on two methods: linear method and neutron porosity cross-plots. From these two results, we choose the minimum value due to: Fundamentals of Log Interpretation. The shale volume in two wells 1 and 2 in the Azadegan oil field in the north of the Dezful structural zone has been calculated using gamma ray log and neutron-density and neutron-porosity cross plot. The sequence stratigraphic analysis by the Pruned Exact Linear Time algorithm of the studied sedimentary rocks in two wells shows that the Kazhdumi Formation in wells 1 and 2 consists of 69 and 76 sedimentary sequences of the 5th order, respectively. This sedimentary sequence includes transgressive sequence systems tracts, highstand systems tract and low stand systems tract. Keywords: Kazhdumi Formation, Azadegan oil field, Pruned Exact Linear Time algorithm, sequence stratigraphy, transgressive sequence systems tracts, highstand systems tract, low stand systems tract, Southwest of Iran. |
